    Towards Smart Behavior of Agents in Evacuation Planning Based on Local Cooperative Path Finding

  • Original language description

    We address engineering of smart behavior of agents in evacuation problems from the perspective of cooperative path finding (CPF) in this paper.We introduce an abstract version of evacuation problems we call multi-agent evacuation (MAE) that consists of an undirected graph representing the map of the environment and a set of agents moving in this graph. The task is to move agents from the endangered part of the graph into the safe part as quickly as possible. Although the abstract evacuation task can be solved using centralized algorithms based on network flows that are near-optimal with respect to various objectives, such algorithms would hardly be applicable in practice since real agents will not be able to follow the centrally created plan. Therefore we designed a decentralized evacuation planning algorithm called LC-MAE based on local rules derived from local cooperative path finding (CPF) algorithms. We compared LC-MAE with near-optimal centralized algorithm using agent-based simulations in multiple real-life scenarios. Our finding it that LC-MAE produces solutions that are only worse than the optimum by a small factor. Moreover our approach led to important observations about how many agents need to behave rationally to increase the speed of evacuation. A small fraction of rational agents can speed up the evacuation dramatically.
